Re-adjust according to specifications. Blow molding machine market demand is different Bottle blowing machine market demand is different. During the rapid development of plastic bottle packaging in the past, the domestic bottle blowing machine industry is also rapidly emerging. The production and development skills of blow molding machines are constantly shrinking with the international advanced level. It should be said that the rapid development of bottle blowing machine companies is inseparable from the rapid growth of the domestic economy in the past few decades. At present, the domestic economic situation is facing structural adjustments and deepening reforms. The addition of plastic bottle packaging has also initially slowed down. The market demand for blow molding machines has also initially declined. Blowing machine companies are facing a different market environment and challenges from the past, and demand for active improvement. First of all, for domestic and European and American plastic bottle production professions, with the increase in labor costs, coupled with economic transformation and upgrading, the needs of the two shopping malls will become more and more similar. The automation requirements for the blow molding machine will become higher and higher, and the production efficiency will also become higher and higher. Therefore, in these two markets, our blow molding machine companies should focus on the automated production of blow molding machines. Secondly, with regard to domestic blow molding machine companies, in order to ensure that the company has added shopping malls, it is necessary to go out and actively develop shopping malls in some developing regions and regions in Asia, Africa and Latin America. Regarding this market, in terms of the demand for bottle blowing machines, the main points will consider the price of the bottle blowing machine and other factors. The middle and low-end bottle blowing machine market should explore these local areas.
